The average home isn’t anywhere near as secure as we’d like to think. Worse than that, the conventional wisdom that is passed off as “home security advice” is just about worthless. All it does is to help keep honest people honest—not keep the dishonest out. Why, you can kick the average front door with a deadbolt wide open!
The problem is that most home security measures don’t take into consideration a determined attack by armed enemies. All they do is keep out people who want to quietly sneak into your home. If someone is willing to make noise, those measures won’t do a thing to keep him out. After all, a locked window isn’t much of a deterrent to an attacker with a rock in hand.
